G'day all from sunny Brisbane in Queensland Australia

I have a 2005 CBR600RR stock standard but have recently started having rear wheel lock up for no reason at all. Pretty scary stuff especially when my pillion nearly cops a fall. It is still under warranty so if anyone has experienced this please let me know. It happens at low speeds so far and not repeatedly. At first I thought it was after all the components had got wet after wet weather riding but yesterday was a beaut dry day and it got completely sideways...without my permission.

 

check your rear brake, chain, sprocket and axle for over tightening or otherwise abnormal specification.
